I've always struggled with Trig, as things like pi seemed abstract to me. With this one video it all makes so much more sense. Thank you

Don't feel bad...feel HAPPY that you found my channel:) I look forward to being your YouTube teacher thru this math course, and THANKS for choosing my channel to learn from! Please share with your classmates if you think they too might benefit and remind them to SUBSCRIBE to show their support and help my channel groW.

Thanks for not giving up the search...I have added more keywords to the search list after reading your comment, so thanks too for pointing that out:) I appreciate the help.

40 years old and I just now learned where 3.14 comes from. Hopefully my son will ask me about this some day so I can look smart!

When you explained where radians come from and how they are related to angles, I was just totally mindblown. I literally just paused the video and smiled for a few minutes. You are made to be a teacher. Thank you so much. Keep doing what you're doing! Already subbed :)

I used to struggle understanding the connection between radians and degrees and was frustrated most of the time now that I know the history behind radians and how they cam about it all makes sense my fear just dissipated. I hope to be as thorough and day when I teach my students here in South Africa. I am becoming more and more excited with every video I watch.

Because arcsin as a restricted function can only give you answers between -90 to 90 or the equivalent radian measures. It is not that it does not work, it is giving you a usable angle that has the same reference angle as the angle you are seeking in quadrant 2.

@Strees99 Thank you very much for letting me know. I made a temporary correction with Youtube's annotation and will repost with a permanent correction tomorrow so people using ipads can see the correction tomorrow.

Professor. Tarrou, i got a B in trig, thank you. next semester taking pre-calculus, expect you to be there for me.

[ishhynavarro]

I have exams tomorrow on this and you made everything clear! I learned more from you than the whole quarter I'm learning in school. THANK YOU. YOU ARE A GIFT.

[profrobbob]

Thank you for watching and subscribing! I appreciate the support very much. Not sure how well I answered your question...but I hope it made a little bit of sense:)

[profrobbob]

Thanks for watching and glad I have been able to help you with your studies. Sorry but I am not familiar with the test videos you are requesting:( All of my current videos are key-worded so maybe you could search for additional help that way.

[profrobbob]

Thank you for that glowing comment! I'm glad you enjoyed learning from my videos and hope you will continue to make me you go-to math channel:)...and please share with others in my quest to groW!

[profrobbob]

THANK YOU Caden...My wife and I are looking forward to that day:)...and we'll be one step closer thanks to students like you!

[yourfriendprimm]

Man, all your videos are awesome! I'm currently in the Navy and my options are limited and I have to take my math classes online...no instructor. I am currently taking trig and I was struggling at first trying to teach myself from the book, then I found your videos. I am very grateful for them, and I am thankful of the way you break the information down and show all the work in a way that really clicks for me me and I would recommend your video's to anyone! You are a great teacher!

[profrobbob]

Thank You...and thanks for supporting by liking and subscribing!

[profrobbob]

WOW...brave one, aren't you! As long as I continue to get the show of support through comments such as yours, you can bet I will continue to keep posting...it's hard sometimes, to come home after a full day of teaching and teach some more...but the rewards are great when you see how many peoples lives you touch! Good luck with your classes and keep me posted on your progress:)

Thank you for uploading your lesson. I'm 36 years old and it has been almost 20 years since I last took a math class. I only ever got to statistics on my in my last degree. Coming back to school to get a math degree and conquer one of those fears I've had in school my entire life. Your videos let me find out what I need to refresh myself on from algebra before taking on these classes in the future.

[profrobbob]

Just keep watching, learning and preparing…the test will be here before you know it but by then you will be ready to take it with confidence:) Thanks again for watching and I will look forward to hearing your results:)
